GNS 430W vs GNS 480

I've done instructing in the G1000 (430 basically) and found that the
most difficult (at least VFR) thing for pilots to learn is how to
change pages and manipulate the cursor to enter data. However, the 480
is certainly a more capable unit but more difficult in that regard.

I can't image a 480 being more capable than a G-1000 with WAAS.

Well, our G1000 C-182 doesn't have WAAS yet, but I don't expect that
holds will be added during that upgrade. The G1000 works like the 430.
When it comes to holds you go into suspend and you have to drive it
around the hold. The only difference between the G1000 and 430 with
regard to holds/procedure turns is that the G1000 automatically
resequences when inbound vs. the 430 that you have to press the
OBS/SUSPEND button to start sequencing again.

I can only speak to a 530. In a hold in lieu of PT, it automatically
sequences after one circuit, no SUSPEND. When you go into a missed
approach hold it does go into SUSPEND and remains there "forever" until
you decide to leave the hold.

The positive course guidance in a 400/500W is dependent upon having a
roll steering autopilot. I doubt your 182 has a roll steering
autopilot. But, even then, once you have the W upgrade the magenta
flight track will be spot on for a charted hold or procedure turn and
will account for your groundspeed.

Are we speaking of the same thing? In the 480 you tell it to hold, give
it the turn direction, leg length etc and it flys the hold. I've not
seen that in any other GPS product.

Yes, the 182T does. Its not even 1 year old yet. It has a nice KAP140
autopilot. Totally hands off. Flys a full ILS down to minimums w/o
touching it. The only thing it doesn't do is fly the hold.

No, I think you are speaking of holds not in the database. Sounds like
the 480 does a nice job of that. I am speaking of charted approach
chart holds.

It will most likely fly the hold with a W mod.

Did this change in the 430 with WAAS? From my teaching in the 430 and
G1000 when you cross the holding fix it just goes into suspend mode
(with a suggested entry procedure). The 480 actually figures the entry
procedure and flys it, you never touch the yoke. Does the 430 WAAS unit
fly the entry procedure?

If the sim for the GNS430W is to be believed, yes it will, assuming of
course it is coupled with an appropriate AP.

I am really interested to hear how many of us have actually been asked to
fly a Holding pattern by ATC in the recent past ?

In the 400/500 series it goes into suspend and displays a message with
the recommended entry procedure. It does graphically show the entry
track. The 400/500 W series do (I have only used the trainer).

Only one lap around a HIL pattern is allowed then suspend drops out. On
a missed approach hold suspend does not drop out.
